Prince Louis was seen gripping the sweet handwritten note that he made especially for his loving grandmother and grandfather.

He stole the show for a second time with the sweetest message at the Westminister Abbey during the evening hours.

As the six-year-old royal walked with his father by his side and his siblings, he looked adorable in his little suit while holding on to the very special note.

‘Thank you Granny and Grandpa because they always played games with me!’- the note read.

The young royal is known for his cheeky tendencies but this time around, he’s won hearts with the most adorable looks and stares.

He was clearly on his best behavior with his mother by his side at all times. She made sure he knew exactly what to do throughout the evening.

The little prince carried the note and added it to the kindness tree where he smiled and enjoyed the activities alongside others present inside.

Meanwhile, his mother, Princess of Wales, could be seen presiding over him and then going to take part in the yearly carol singing tradition.

She beamed in the color red and looked like a beautiful wrapped gift. Many were happy to see her return to royal duties with a band and looking fresh and healthy like before.
